ceans in tubs in any desired quantity, by extending the 

 area devoted to it. It is simply a question of providing a 

 greater space devoted to plants which provide the food for 

 these little animals, but what their natural food is I do not 

 know. I think it is known, however, what they feed on. 

 I supi)ose it is still more minute life, animal or vegetable, 

 or the plants themselves." 



The Chair said: "Has this plan been pursued to any 

 extent in this country ? ' ' 



Mr. Seal said : " I do not know that it has. My experi- 

 ence has been with other lishes than the trout, but in an 

 amateur way. I am convinced, however, that it is possible 

 to do it on a large scale." 



Dr. Parker said : " It seems to me the question of weight 

 would come in somewhere. It would take a great many of 

 these little objects to make a pound of trout." 



Mr. Seal said : "It takes some time to raise a pound of 

 trout, and I have no doubt but that in the necessary time, 

 enough of these little objects could be raised in a compara- 

 tively small quantity of water to afford^the necessary food. 

 It is my belief that, given the proper conditions, enough of 

 them to rear a yearling trout may be produced in a cubic 

 foot of water." 



^h\ Ford said : ' ' The Pennsylvania Commission has had 

 a practical illustration of the subject of yearling trout by 

 putting, some four years ago, 150 yearling trout in a small 

 spring-water stream, and about 2,000 fry in another stream 

 not far removed from it. The result has been that in the 

 stream where the fry were deposited a much larger pro- 

 portion of trout has been realized than in the other. I do 

 not know what is the practice in New York State, but with 

 us we very seldom send out any trout before the last week 

 in IVFarch, when they have obtained quite a growth. Six or 

 seven years ago we hardly knew what to do with our trout ; 

 the applications were few and far between. During the 

 past year we hatched two and a half millions of trout,
